If you’ve noticed your shrimp constantly swimming up to the water’s surface in your aquarium you may be wondering what’s causing this behavior. There are several potential reasons shrimp exhibit this behavior and it’s important to understand the underlying factors to ensure the health and well-being of your shrimp. In this article, we’ll explore the common causes of shrimp swimming to the top and provide helpful solutions for addressing this issue.
Overview of Potential Causes
Shrimp swimming to the top of the tank can indicate issues with water quality, overfeeding, stress, or lack of oxygen. Here’s a quick overview of each potential cause:
-
Poor water quality – Issues like high ammonia, nitrites, nitrates, and improper pH can lead to shrimp seeking the surface
-
Overfeeding – Excess food causes shrimp to become more active looking for food, swimming upwards.
-
Stress – Sudden changes in parameters, aggressive tank mates, inadequate hiding spots can induce stress.
-
Low oxygen – Inadequate aeration and surface agitation leads to low oxygen, prompting shrimp to surface.
Poor Water Quality
Deteriorating water quality is one of the most common reasons shrimp will gather at the water’s surface. Shrimp are highly sensitive to water parameters like ammonia, nitrites, nitrates and improper pH levels.
When any of these increase to harmful levels, shrimp will exhibit unusual behaviors as they seek relief, including swimming frantically to the top of the tank. It’s critical to regularly test and maintain optimal levels through partial water changes and filtering. Ideal parameters are:
- Ammonia and Nitrites: 0 ppm
- Nitrates: Under 20 ppm
- pH: 6.5-7.5
Sudden water chemistry changes can also cause issues, even if parameters are in the ideal range. Consistency is key for shrimp health.
Overfeeding
Another common culprit for shrimp heading upwards is overfeeding. When excess food accumulates in the tank, shrimp become more active foraging for food. This increased activity leads them all over the tank, including up to the water’s surface.
Overfeeding also contributes to deteriorating water quality by increasing ammonia and nitrates. Uneaten food quickly decays, spiking parameters.
To avoid this issue, feed shrimp only as much as they can consume within a few minutes 1-2 times daily. Remove any uneaten food immediately. This prevents build up and maintains water quality.
Stress
Stress is another factor that can induce frantic swimming behavior in shrimp. Possible stressors include:
-
Sudden changes in water parameters like pH, temperature, hardness. Maintain consistency.
-
Aggressive fish tankmates that may prey on shrimp. Avoid housing predators.
-
Insufficient hiding spaces. Shrimp feel secure with ample decor and plants.
-
Improper population density. Avoid overcrowding.
Addressing sources of stress helps minimize shrimp swimming at the top. Provide a stable, secure environment and compatible tank mates.
Low Oxygen Levels
Inadequate oxygenation can also lead to shrimp gathered at the surface. Dissolved oxygen levels may drop due to poor circulation, lack of surface agitation, or overcrowding. This lack of oxygen motivates shrimp to swim upwards in search of higher oxygenated water.
Ensure proper water movement and aeration. Powerheads and air stones help circulate and oxygenate the tank water. Position filter outflow to agitate the surface. Perform regular maintenance on filter media. Reduce bioload if overcrowded.
What To Do If Shrimp Swim To The Top
If you notice your shrimp suddenly gathered at the top, act quickly to remedy the likely underlying issue:
-
Test water parameters and perform an immediate 20-30% water change if ammonia, nitrites or nitrates are elevated.
-
Reduce feeding amounts if you suspect overfeeding. Siphon out excess waste.
-
Address potential stressors like aggressive fish, lack of hiding spaces or abrupt water changes.
-
Check filter function and circulation. Clean clogged media. Add aeration devices if needed.
-
Look for dead specimens and remove immediately to prevent spiking ammonia.
-
Perform routine partial water changes and gravel vacuuming to maintain clean water.
Persistently swimming to the top is problematic for shrimp health. Identifying and quickly fixing the cause will restore normal shrimp behavior and prevent losses. With proper care, your shrimp will thrive without constantly heading to the surface!
Shrimp aren’t breeding
You may have had your shrimp for months and not seen any berried females. That’s because they’re very good at hiding, so babies can come out of nowhere.
It’s normal for shrimp in new tanks to wait a few weeks or months before they start to breed. They want to get comfortable with their new surroundings first.
It’s possible that the babies are hatching but are having a hard time surviving. Are you sure they’re not breeding?
A lack of biofilm in the tank is one of the main reasons baby shrimp might struggle.
You may also notice dropped eggs in your tank, on the substrate or floating around near some plants. It’s possible for dropped eggs to still hatch with a little effort.
- Have they been in the tank for long enough?
- Is it warm enough? Low temperatures can reduce breeding
- Is there enough food for them?
- Do they have enough hiding places?

️ 5 Shrimp Keeping Mistakes to Avoid! THESE MISTAKES ARE MOST OFTEN MADE BY NEW SHRIMP KEEPERS
Why do shrimp swim around a lot?
The main key reasons for shrimp swimming around a lot are: If you’ve only just added the shrimp into a new tank, it’s perfectly normal for them to either start exploring the tank or to hide. Typically, most shrimp will immediately try to seek protection, climbing into small gaps and hiding amongst plants until they feel more comfortable.
What are the side effects of eating shrimp?
Shrimp allergy can be identified from signs and symptoms that appear after consuming shrimp or smelling it, such as itching, the appearance of red plaques on the skin, swelling in the face, especially in the eyes and mouth, and in the throat creating the feeling of a lump in the throat.
Why do shrimp stay at the top?
Doing so allows them to exploit dissolved oxygen more efficiently. However, shrimp may also stay at the top due to elevated toxins, such as ammonia, copper, and chlorine. As we move forward in this article, I will share a few other reasons for the phenomenon, including the case in which upward swimming is perfectly normal.
Why do ghost shrimps swim to the top?
One of the main reasons for ghost shrimps swimming to the top is the absence of a cycled tank. Now, what does it mean? A cycled tank means an appropriate habitat for the ghost shrimps. The nitrate, KH, GH, TDS, pH, noise, light intensity, temperature- everything will be in favor of the ghost shrimps.
